• SDK fixes from master branch:
  • Fix issue where MQTT ReceiveAsync with cancellation token always returns null.
  • Fix issue where MQTT packet id becomes 0 on 32kth messages sent, which caused MQTT connection to drop.

  • Fix issue where AMQP SendTwinPatchAsync with cancellation token doesn’t cancel after cancellation token is cancelled.
  • Revert to throw TimeoutException if operation times out instead of IotHubCommunicationException.
  • Revert to throw OperationCancelledException if operation is cancelled instead of IotHubCommunicationException.
  • Fix connection string parser to allow special characters such as semicolon.

  • Add clarification to connection status callback documentation for HTTP.
  • Add clarification to device operation timeout documentation.

  • Fix issue where ModuleClient configured with Mqtt_Tcp_Only fails to reconnect after edgeHub restart then never recovers (#1239)
  • When using AMQP, application properties with a null value will now be sent to the hub, matching MQTT/HTTP behavior (#919)

  • MqttTransportSettings.CertificateRevocationCheck and AmqpTransportSettings.CertificateRevocationCheck are now linked with TlsVersions.Instance.CertificateRevocationCheck property.
  • Made Message class partially cloneable - to be able to copy system properties to a new instance (#1923). See Message.CloneWithBody method.

  • Deprecate file upload APIs in favor of new, more granular APIs that allow users to use their own Azure storage SDK to do the actual upload

Microsoft.Azure.Devices.1.27.1-preview-001

• Rename DeviceStreamResponse.Url to DeviceStreamResponse.Uri, since it represents a Uri.
  • NOTE: This is a breaking change for DeviceStreaming APIs.
• SDK fixes from master branch:
  • Add modelId support for PnP summer refresh
  • Upgraded Newtonsoft.Json dependency to 12.0.3
  • Fix proxy handling on HTTP for requests with per-request timeout.
  • Centralize TLS version choice, prefer None where possible.
  • Fixed proxy handling for Http client.
  • IotHubClientWebSocket.ConnectAsync method now respects the SslProtocol value specified in TlsVersions.Instance.Preferred.
  • Dropped support for .NET Standard 1.3, and added support for .NET Framework 4.7.2.
  • Enables new security functionality to specify how hub should authenticate when working with a storage account when running import/export devices jobs.
    • New enum StorageAuthenticationType to specify key-based or identity-based authentication.
    • New property JobProperties.StorageAuthenticationType for use in import/export devices jobs.
    • Added two overloaded methods: RegistryManager.ImportDevicesAsync and RegistryManager.ExportDevicesAsync. The overloads take a JobProperties instance so the user can pass all required and any optional parameters.
    • Two factory methods to make it easier to call ImportDevicesAsync and ExportDevicesAsync, making it clear which properties are required and which are optional. They are JobProperties.CreateForInportJob and JobProperties.CreateForExportJob respectively.
    • Removed two unreferenced classes: ImportDevicesRequest and ExportDevicesRequest.
  • Reuse HttpClient instances (#1276), avoiding a known issue with HttpClient.Dispose() that can cause TCP socket exhaustion under heavy load.
  • Use latest Service API version that is available in all regions
  • Add Support for .NET Standard 2.1
  • Add twin array support
  • Update JobQuotaExceededException to include the associated http error reason
  • Code clean up in IotHubConnectionStringBuilder based on coding standards
